Description

本発明は、手摺の自在連結具に関し、さらに詳しくは、傾斜地や手摺の取付方向が多岐にわたるような多様な形状の手摺を少ない部材で設置することを可能とする手摺の自在連結具に関する。   The present invention relates to a handrail universal connector, and more particularly, to a handrail universal connector that allows a variety of shapes of handrails to be installed with a small number of members such as slopes and attachment directions of handrails.

設置場所の状況に応じて手摺の取り付け角度が適宜に設定できる各種の手摺連結具が提供されている。しかし、そのような機能を備えた従来の手摺連結具は、手摺の角度調整を可能とせんがために様々な機構が盛り込まれ、その結果、構造が複雑なものとなっていた。また、終端部に配置される手摺の連結具には通常1本の手摺が取り付けられ、中間の手摺の連結具には二又はそれ以上の手摺が取り付けられる。したがって、終端部用の手摺の連結具と中間部用の手摺の連結具を用意する必要があり、部品点数が増加すると共に、設置の手間やコストも高いものとなっていた。そのため、設置に手間がかからずしかも部品点数が少なく設置コストも安い手摺の連結具が望まれていた。   Various handrail couplers are provided in which the handrail attachment angle can be appropriately set according to the situation of the installation location. However, the conventional handrail coupler having such a function cannot be adjusted in the angle of the handrail, so various mechanisms are incorporated, and as a result, the structure is complicated. In addition, one handrail is usually attached to the handrail connector disposed at the end portion, and two or more handrails are attached to the intermediate handrail connector. Therefore, it is necessary to prepare a handrail connector for the terminal portion and a handrail connector for the intermediate portion, which increases the number of parts and increases the labor and cost of installation. Therefore, there has been a demand for a handrail connector that requires less labor for installation, has fewer parts, and is less expensive to install.

そのような手摺の連結具も次第に提供されはじめており、例えば、特許文献1に開示された自在継手は、上下一対の半球ブロックの2部材と、垂直方向に回動自在の手摺バー連結用のブラケットの2部材と、半球ブロックを水平回動自在の球体として支柱上端に軸支固定する支持ブロックの1部材の合計5部材によって自在継手を構成するようになっており、これによって手摺バーの3次元的な連結を可能とすると共に、連結作業を容易にし、さらに少ない部材によって手摺を構成することを可能としたものである。   Such a handrail connector is also gradually provided. For example, the universal joint disclosed in Patent Document 1 includes two members of a pair of upper and lower hemispherical blocks and a bracket for connecting a handrail bar that is rotatable in the vertical direction. And a total of five members, i.e., one member of a support block that is pivotally fixed to the upper end of the column as a horizontally rotatable sphere as a hemispherical block, thereby forming a universal joint. In addition to making it possible to perform a simple connection, the connection work is facilitated, and a handrail can be configured with fewer members.

一方、特許文献2には、縦型手摺の設置構造が開示されており、縦型手摺に取り付ける以下の構成を有するポールサポートブラケットが示されている。すなわち、ポールサポートブラケットは、球形部を端面部に有するように一体的に構成された複数のパイプソケットと、上面部の周方向に球形部の下半部を支持する半球形状の球状凹部が形成された下側部材と、下面部の周方向に下側部材の球状凹部と同一の配置、同一の大きさの半球形状で、球形部の上半部を支持する複数の球状凹部が形成され、下側部材の上に重ね合わされる上側部材を備えて構成され、上側部材と下側部材に形成された球状凹部内にパイプソケットの球形部を収容して挟持することにより、球形部をボールジョイントのように回転自在に支持するようになっている。また、壁取付ブラケットもポールサポートブラケットと同様に、壁固定部材と蓋部材に形成された球状凹部内にパイプソケットの球形部を収容して挟持することにより、球形部をボールジョイントのように回転自在に支持するようになっている。   On the other hand, Patent Document 2 discloses an installation structure of a vertical handrail, and shows a pole support bracket having the following configuration attached to the vertical handrail. That is, the pole support bracket is formed with a plurality of pipe sockets that are integrally configured to have a spherical portion at the end surface portion, and a hemispherical spherical concave portion that supports the lower half portion of the spherical portion in the circumferential direction of the upper surface portion. A plurality of spherical recesses that support the upper half of the spherical portion in the same arrangement as the spherical recesses of the lower member in the circumferential direction of the lower member, and the same size hemispherical shape, The ball member is configured by including an upper member that is overlaid on the lower member, and the spherical portion of the pipe socket is accommodated and held in a spherical recess formed in the upper member and the lower member, whereby the spherical portion is connected to the ball joint. It is designed to be supported so that it can rotate freely. Also, the wall mounting bracket, like the pole support bracket, rotates the spherical part like a ball joint by accommodating and holding the spherical part of the pipe socket in a spherical recess formed in the wall fixing member and the lid member. Supports freely.

そして、手摺バーが不用意に動くことを防止するために蓋部材を貫通して球形部の表面に至る止めネジによって球形部を締め付けることで手摺バーを固定するようになっている。尚、同様の構成を有するブラケットは特許文献3にも開示されている。   In order to prevent the handrail bar from inadvertently moving, the handrail bar is fixed by tightening the spherical portion with a set screw that penetrates the lid member and reaches the surface of the spherical portion. A bracket having the same configuration is also disclosed in Patent Document 3.

その他、本願発明者も、複雑な形状の傾斜面に対しても現場において簡単に手摺を設置することができる手摺取付具を発明し、種々の特許出願を行っている(特許文献4、5)。   In addition, the present inventor has also invented a handrail attachment that can easily install a handrail even on an inclined surface having a complicated shape, and has filed various patent applications (Patent Documents 4 and 5). .

特開2007−92359号公報JP 2007-92359 A 特開2004−316089号公報JP 2004-316089 A 特開2004−316091号公報JP 2004-316091 A 特開2003−119988号公報Japanese Patent Laid-Open No. 2003-119988 国際公開第2003/035997号パンフレットInternational Publication No. 2003/035997 Pamphlet

しかし、引用文献1に開示された自在継手にあっては、最終端の手摺を連結するための継手については言及されておらず、最終端の継手の場合には一方側のブラケットに手摺バーが連結されない状態となるか、またはブラケットが形成されていない最終端用の半球ブロックを別途用意する必要がある。   However, in the universal joint disclosed in Cited Document 1, there is no mention of a joint for connecting the handrail at the end, and in the case of the joint at the end, a handrail bar is provided on one bracket. It is necessary to prepare a hemispherical block for the final end that is not connected or has no bracket.

また、特許文献2、3に開示されたポールサポートブラケットは、蓋部材を貫通して球形部の表面に至る止めネジのみで球形部を固定することによって手摺バーを固定しているため、止めネジの緩みによって手摺バーがガタつくおそれがある。また、止めネジは球形部の表面に接触してその表面を押圧しているだけなので手摺バーの取り付け方向を軸とする回転方向に大きな荷重がかかった場合には止めネジの押圧力が手摺バーの回転を阻止できず手摺バーがその取り付け方向を軸として回転してしまうおそれがある。掴んだ手摺がくるりと回転してしまうとなれば極めて危険であり、転倒等の重大事故に至るおそれもある。   Further, the pole support brackets disclosed in Patent Documents 2 and 3 fix the handrail bar by fixing the spherical portion only with a set screw that passes through the lid member and reaches the surface of the spherical portion. There is a risk that the handrail bar will rattle due to looseness. In addition, since the set screw only touches the surface of the spherical part and presses the surface, the pressing force of the set screw is applied to the handrail bar when a large load is applied in the rotation direction around the handrail bar mounting direction. There is a risk that the handrail bar will rotate around the mounting direction as a shaft. If the grab handrail rotates around it, it is extremely dangerous and may cause a serious accident such as a fall.

そこで、本発明は、かかる問題点に鑑みなされたもので、傾斜地や多角形など多様な形状の手摺を最小限の部品点数で設置することが可能な手摺の自在連結具を提供することを目的とする。
また、本発明は、そのような手摺の自在連結具において、手摺の取り付け方向を軸とする回転方向に大きな荷重がかかった場合でも手摺が回転することなく安全確実に固定することが可能な手摺の自在連結具を提供することを目的とする。
Accordingly, the present invention has been made in view of such problems, and an object of the present invention is to provide a handrail universal coupler that can install handrails of various shapes such as slopes and polygons with a minimum number of parts. And
In addition, the present invention provides a handrail that can be securely and securely fixed without rotation of the handrail even when a large load is applied in the rotation direction about the handrail attachment direction. An object of the present invention is to provide a universal coupler.

以下、本発明に係る手摺の自在連結具の一実施形態について図面を参照しつつ説明する。図1は本発明に係る手摺の自在連結具の一実施形態の斜視図である。   Hereinafter, an embodiment of a universal handrail connector according to the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment of a handrail universal connector according to the present invention.

図示された自在連結具1は、概略として、略球形状のジョイント部21を備えた手摺保持体20と、ジョイント部21を可動可能に保持する本体10と、手摺保持体20に取り付けられた手摺5がその取り付け方向を軸として回転しないように阻止する回転防止機構とを備えて構成されている。   The illustrated universal coupler 1 generally includes a handrail holding body 20 having a substantially spherical joint portion 21, a main body 10 that movably holds the joint portion 21, and a handrail attached to the handrail holding body 20. 5 is provided with a rotation prevention mechanism for preventing the rotation with respect to the mounting direction as an axis.

手摺保持体20は、図2に示すように、その一端側に手摺5を取り付けるための手摺取付部25を備えると共に、他端側には略球形状のジョイント部21を備えて構成されている。手摺取付部25は、その内部に手摺5の端部を挿入可能なように中空状に形成され、手摺取付部25に手摺5を挿入した状態で手摺保持体20の側面に穿設されたネジ孔20aから図示しないネジ部材で締着することにより手摺5を手摺保持体20に固定するようになっている。手摺取付部25は、取り付けるべき手摺の端部形状に即して形成されていれば良く、円筒形状をはじめ、楕円形状、多角形状等各種の形状が採用可能である。   As shown in FIG. 2, the handrail holding body 20 includes a handrail mounting portion 25 for mounting the handrail 5 on one end side thereof, and a substantially spherical joint portion 21 on the other end side. . The handrail mounting portion 25 is formed in a hollow shape so that the end portion of the handrail 5 can be inserted therein, and is a screw formed on the side surface of the handrail holding body 20 with the handrail 5 inserted into the handrail mounting portion 25. The handrail 5 is fixed to the handrail holding body 20 by fastening with a screw member (not shown) from the hole 20a. The handrail attaching portion 25 only needs to be formed according to the shape of the end portion of the handrail to be attached, and various shapes such as a cylindrical shape, an elliptical shape, and a polygonal shape can be adopted.

一方、ジョイント部21は、後述する収容部11に収容保持される略球形状をとされ、その表面には凸状部23が突出するようにして設けられている。この凸状部23は手摺5の回転を防止するための回転防止機構を構成する。本実施形態では凸状部23は2か所に設けられており、その位置関係は、いわゆる北極と南極のように、球の中心に対して点対称の位置で、取付部21aに対してそれぞれ90°の位置に配置されている。尚、凸状部23はジョイント部21に少なくとも1ヶ所、好ましくは2ヶ所に設けられているとよい。手摺保持体20は強度的な信頼性が要求されるため、例えば、ステンレスなどの金属製材料で形成することが好ましいが、強度の対応が可能であれば合成樹脂などによって形成してもよい。   On the other hand, the joint portion 21 has a substantially spherical shape that is housed and held in the housing portion 11 to be described later, and a convex portion 23 is provided on the surface thereof. The convex portion 23 constitutes a rotation prevention mechanism for preventing the handrail 5 from rotating. In this embodiment, the convex part 23 is provided in two places, and the positional relationship is point-symmetric with respect to the center of the sphere, as in the so-called North Pole and South Pole, with respect to the attachment part 21a. It is arranged at a position of 90 °. In addition, the convex part 23 is good to be provided in the joint part 21 at least at one place, preferably at two places. Since the handrail holding body 20 is required to have high reliability, for example, it is preferably formed of a metal material such as stainless steel, but may be formed of a synthetic resin or the like if the strength can be accommodated.

本体10は、上部本体12と下部本体13を組み合わせることによって形成されており、手摺保持体20のジョイント部21を可動可能に収容する収容部11が互いに対向する位置の2か所に設けられている。   The main body 10 is formed by combining the upper main body 12 and the lower main body 13, and the accommodating portions 11 that movably accommodate the joint portions 21 of the handrail holder 20 are provided at two positions facing each other. Yes.

上部本体12は、図3及び図4に示すように、球を半割状にした形状をなし、その中心部には頂部からその中心部を貫通するようにしてネジ孔12dが穿設されている。上部本体12の底面、すなわち後述する下部本体13と互いに接合される接合面には、図4に最も良く示されているように、ジョイント部21を収容するための収容部11を形成するための凹部12aが形成されている。凹部12aは、半球状の上部本体12の接合面を形成する大円の中心に対して点対称の位置に二か所に設けられている。   As shown in FIGS. 3 and 4, the upper body 12 has a shape in which a sphere is halved, and a screw hole 12 d is formed in the center of the top body 12 so as to penetrate the center from the top.

On the bottom surface of the upper body 12, that is, the joint surface that is joined to the lower body 13 described later, as best shown in FIG. 4, an accommodation portion 11 for accommodating the joint portion 21 is formed. A recess 12a is formed. The recesses 12 a are provided at two positions that are point-symmetric with respect to the center of the great circle that forms the joint surface of the hemispherical upper body 12.

また、上部本体12の接合面には凹部12aの縁部に沿って、凸状部23が当接してその動きを規制するための上側当接部12cが形成されている。この上側当接部12cと後述する下部本体13の下側当接部13cとによって手摺保持体20に取り付けられた手摺5がその取付方向を軸とする回転をしようとした際に凸状部23が当接してその回転を阻止する回転防止機構を構成する当接部15(図7参照)が形成される(図9(c)参照)。   Further, an upper abutting portion 12c is formed on the joint surface of the upper body 12 along the edge of the concave portion 12a so that the convex portion 23 abuts and restricts its movement. When the handrail 5 attached to the handrail holding body 20 by the upper contact portion 12c and the lower contact portion 13c of the lower main body 13 described later tries to rotate about the attachment direction, the convex portion 23 is formed. A contact portion 15 (see FIG. 7) that constitutes a rotation prevention mechanism that prevents the rotation of the contact is formed (see FIG. 9C).

これに対して、上部本体12と組み合わされる下部本体13は、図5及び図6に示すように、球形を半割した形状を有しており、その接合面形状は概ね上部本体12と同様の構成を備えている。すなわち、中心部には内部を貫通するようにしてネジ孔13dが穿設されており、上部本体12のネジ孔12dと連通してネジ部材17(図8参照)が締着されるようになっている。これにより、上部本体12と下部本体13とが一体に組み合わされて本体10を形成する。   On the other hand, the lower main body 13 combined with the upper main body 12 has a half-spherical shape as shown in FIGS. 5 and 6, and the joint surface shape is substantially the same as that of the upper main body 12. It has a configuration. That is, a screw hole 13d is formed in the center so as to penetrate the inside, and the screw member 17 (see FIG. 8) is fastened in communication with the screw hole 12d of the upper body 12. ing. Thereby, the upper body 12 and the lower body 13 are integrally combined to form the body 10.

また、図6に最も良く示されているように、上部本体12と接合される下部本体13の接合面には凹部13aが形成されており、上述の上部本体12の凹部12aと一体となってジョイント部21を収容するための収容部11を形成する。凹部13aは、半球状の下部本体13の接合面を形成する大円の中心に対して点対称の位置に二か所に設けられている。   Further, as best shown in FIG. 6, a recess 13a is formed on the joint surface of the lower body 13 joined to the upper body 12, and is integrated with the recess 12a of the upper body 12 described above. The accommodating part 11 for accommodating the joint part 21 is formed. The recesses 13a are provided at two points symmetrical with respect to the center of the great circle forming the joining surface of the hemispherical lower main body 13.

さらに、下部本体13の接合面には、凹部13aの縁部に沿って凸状部23が当接してその動きを規制する下側当接部13cが形成されている。この下側当接部13cと上側当接部12cとによって、上述したように、手摺保持体20に取り付けられた手摺5がその取付方向を軸とする回転をしようとした際に凸状部23が当接してその回転を阻止する回転防止機構を構成する当接部15(図7参照)が形成される(図9(c)参照)。尚、下部本体13の接合面には上部本体12との位置合わせを行うための案内片13eが設けられている。   Furthermore, a lower contact portion 13c is formed on the joint surface of the lower main body 13 so that the convex portion 23 abuts along the edge of the concave portion 13a and restricts its movement. As described above, the lower contact portion 13c and the upper contact portion 12c allow the handrail 5 attached to the handrail holding body 20 to rotate when the attachment direction is an axis. A contact portion 15 (see FIG. 7) that constitutes a rotation prevention mechanism that prevents the rotation of the contact is formed (see FIG. 9C). A guide piece 13e for positioning with the upper body 12 is provided on the joint surface of the lower body 13.

また、下部本体13には立設部19と、さらに立設部19の下端部に支柱7を取り付けるための支柱保持体30が一体に形成されている。支柱保持体30には中空状の支柱取付部35が形成され、手摺保持体20と同様に、その内部に支柱7が挿入されるようになっている。そして、支柱保持体30の側面に穿設されたネジ孔30aを介してネジ部材を締着することにより支柱7への取り付けが行われるようになっている。   Further, the lower main body 13 is integrally formed with a standing portion 19 and a column support body 30 for attaching the column 7 to the lower end portion of the standing portion 19. A hollow column attachment portion 35 is formed in the column support body 30, and the column 7 is inserted into the inside like the handrail support body 20. And the attachment to the support | pillar 7 is performed by fastening a screw member through the screw hole 30a drilled in the side surface of the support | pillar holding body 30. As shown in FIG.

以上のようにして形成された本体10に可動可能に取り付けられた手摺保持体20は、ジョイント部21を中心として水平方向及び垂直方向へ自由に可動させることが可能となる。   The handrail holding body 20 movably attached to the main body 10 formed as described above can be freely moved in the horizontal direction and the vertical direction around the joint portion 21.

ここで、上部本体12と下部本体13を組み合わせることによって形成される本体10の収容部11の開口の大きさ及び形状を適宜調整することによって水平方向の手摺5の振り角θ1(図9(a)参照)及び上下方向の振り角θ2(図9(b)参照)の範囲調整を行うことができるのでこの点について説明する。すなわち、図3及び図5に示された上部本体12と下部本体13の開口部12b、13bの幅サイズを狭くすればジョイント部21の取付部21aが僅かの振り角で開口部12b、13bの周縁部と接触することになるので手摺5の水平方向における設置角度の許容範囲は小さくなる。   Here, the swing angle θ1 of the handrail 5 in the horizontal direction is adjusted by appropriately adjusting the size and shape of the opening of the accommodating portion 11 of the main body 10 formed by combining the upper main body 12 and the lower main body 13 (FIG. 9A )) And the vertical swing angle θ2 (see FIG. 9B) can be adjusted, and this point will be described. That is, if the width sizes of the openings 12b and 13b of the upper main body 12 and the lower main body 13 shown in FIGS. 3 and 5 are reduced, the attachment portion 21a of the joint portion 21 is formed with a slight swing angle between the openings 12b and 13b. Since it comes into contact with the peripheral edge, the allowable range of the installation angle in the horizontal direction of the handrail 5 becomes small.

それとは逆に、開口部12b、13bの幅サイズを広くすれば手摺5の水平方向における設置角度の許容範囲は大きくなる。また、開口部12b、13bの高さサイズを狭くすれば手摺5の上下方向における設置角度の許容範囲は小さくなる。それとは逆に、開口部12b、13bの高さサイズを広くすれば手摺5の上下方向における設置角度の許容範囲は大きくなる。尚、ジョイント部21に設ける凸状部23を1ヶ所に設ける場合は、手摺保持体20を可動させた際に凸状部23が開口部12b、13bから外側へ位置するようなことがないように収容部11の開口部12b、13bの大きさを小さくすることが必要となる。そうでないと凸状部23が当接部15に当接せず手摺5がその取付方向を軸とする回転するおそれがあるからである。   On the contrary, if the width of the openings 12b and 13b is increased, the allowable range of the installation angle in the horizontal direction of the handrail 5 is increased. Moreover, if the height size of the openings 12b and 13b is reduced, the allowable range of the installation angle in the vertical direction of the handrail 5 is reduced. On the contrary, if the height of the openings 12b and 13b is increased, the allowable range of the installation angle in the vertical direction of the handrail 5 is increased. In the case where the convex portion 23 provided in the joint portion 21 is provided at one place, the convex portion 23 is not positioned outward from the openings 12b and 13b when the handrail holding body 20 is moved. In addition, it is necessary to reduce the size of the openings 12b and 13b of the accommodating portion 11. Otherwise, the convex portion 23 does not come into contact with the contact portion 15, and the handrail 5 may rotate around the mounting direction.

また、収容部11の位置を上部本体12及び下部本体13のそれぞれの接合面を形成する大円の中心に対して、例えば、点対称の位置に設け、それぞれの手摺保持体20、20の最大振り角を90°とすれば、2つの手摺保持体20、20よって形成される角度は90〜180°となりその範囲で手摺5の設置角度を調整することが可能となる。一方、図10(b)に示すように、収容部11を形成する位置を上部本体12及び下部本体13のそれぞれの接合面を形成する大円の中心に対して非対称の位置に設けることで2つの手摺保持体20、20の取り付け角度を鋭角又は鈍角とすることができる。   In addition, the position of the accommodating portion 11 is provided, for example, at a point-symmetrical position with respect to the center of the great circle that forms the joint surface of each of the upper main body 12 and the lower main body 13, and the maximum of the handrail holding bodies 20, 20 If the swing angle is 90 °, the angle formed by the two handrail holders 20 and 20 is 90 to 180 °, and the installation angle of the handrail 5 can be adjusted within the range. On the other hand, as shown in FIG. 10B, the position where the accommodating portion 11 is formed is set to be asymmetrical with respect to the center of the great circle that forms the joint surfaces of the upper body 12 and the lower body 13. The attachment angle of the two handrail holding bodies 20, 20 can be an acute angle or an obtuse angle.

次に、上述の自在連結具1を用いて手摺を設置した一例を図11に示す。図示された手摺は、終端部の自在連結具1aと終端部の自在連結具1aと手摺5を介して連結される自在連結具1bと、自在連結具1bと手摺5を介して連結される自在連結具1cによって形成されており、各自在連結具1a、1b、1cはそれぞれ所定の位置に設置された支柱7の上端部に取り付けられている。ここで、終端部の自在連結具1aの2つの収容部11のうち一方側の収容部11には手摺5を取り付ける必要がないので当然ながら手摺保持体20が取り付けられていない。   Next, an example in which a handrail is installed using the above-described universal coupler 1 is shown in FIG. The handrail shown in the figure is freely connected via a universal connector 1a at the end portion, a universal connector 1b connected to the universal connector 1a at the end portion via a handrail 5, and a universal connector 1b via a handrail 5. Each of the universal couplers 1a, 1b, and 1c is attached to an upper end portion of a column 7 installed at a predetermined position. Here, since there is no need to attach the handrail 5 to one of the two accommodating portions 11 of the endless universal coupler 1a, the handrail holding body 20 is not naturally attached.

しかし、一方側だけに手摺保持体20を取り付け、もう一方側になにも取り付けずに上部本体12と下部本体13で一方側の手摺保持体20のジョイント部21を挟持させた場合、上部本体12と下部本体13の締着時の均等な荷重のバランスを図ることができない。そのため、収容部11に手摺保持体20のジョイント部23を保持させない場合には、図8に示すように、球状部材40を収容することにより上部本体12と下部本体13の締着時の均等な荷重のバランスを図る。球状部材40は、手摺保持体20のジョイント部21と略同様の大きさの外形形状を備えた略球形状の部材であり、ジョイント部21と同じ材質の材料で形成することが好ましい。これにより、終端部に設置する自在連結具1aの手摺保持体20も本体10に安全に保持される。   However, when the handrail holding body 20 is attached only to one side and the joint portion 21 of the handrail holding body 20 on one side is sandwiched between the upper body 12 and the lower body 13 without attaching anything to the other side, the upper body It is impossible to balance the load evenly when the lower body 12 and the lower body 13 are fastened. Therefore, when the joint portion 23 of the handrail holding body 20 is not held in the storage portion 11, the spherical member 40 is stored as shown in FIG. 8 to equalize the upper main body 12 and the lower main body 13 during fastening. Balance the load. The spherical member 40 is a substantially spherical member having an outer shape substantially the same size as the joint portion 21 of the handrail holding body 20, and is preferably formed of the same material as the joint portion 21. Thereby, the handrail holding body 20 of the universal connector 1 a installed at the terminal end is also safely held by the main body 10.

以上のように、自在連結具1によれば、手摺保持体20は、本体10のどの収容部11にも取り付け可能となっているので、その結果、上部本体12、立設部19と支柱保持体30を備えた下部本体13、手摺保持体20、球状部材40及びネジ部材17の僅かの部材によって設置場所の状況に応じた手摺の設置が可能となる。また、部品の管理及び在庫管理が大幅に軽減され、ひいては設置コストも大幅に低減することが可能となる。   As described above, according to the universal coupler 1, the handrail holding body 20 can be attached to any housing portion 11 of the main body 10, and as a result, the upper main body 12, the standing portion 19 and the column holding member The handrail can be installed according to the situation of the installation location by the lower body 13 including the body 30, the handrail holding body 20, the spherical member 40, and the few members of the screw member 17. In addition, parts management and inventory management are greatly reduced, and as a result, installation costs can be greatly reduced.

次に、上述した自在連結具1の設置方法及び動作について図11を参照しつつ説明する。手摺を設置すべき場所に所定の間隔をもってそれぞれ支柱7、7を立設する。立設された各支柱7、7の上端部を支柱保持体30の支柱取付部35内に挿入するようにして自在連結具1を取り付ける。自在連結具1の取り付けは、支柱保持体30の側面に穿設されたネジ孔30aからネジ部材を締着することにより行う。そして、一端に手摺保持体20が取り付けられた手摺5を終端部の自在連結具1aへの取り付けを行う。すなわち、ネジ部材17を緩め、上部本体12と下部本体13の一方側の開口部12b、13bから凹部12a、13aへ手摺保持体20のジョイント部21を挿入すると共に、他方側の凹部12a、13aへは球状部材40を装填する。そして、手摺保持体20が可動する程度にネジ部材17を締め付ける。   Next, the installation method and operation | movement of the universal coupler 1 mentioned above are demonstrated, referring FIG. Supports 7 and 7 are erected at predetermined intervals at locations where handrails are to be installed, respectively. The universal connector 1 is attached so that the upper end portions of the upright columns 7 and 7 are inserted into the column mounting portions 35 of the column holding body 30. The universal connector 1 is attached by fastening a screw member from a screw hole 30a formed in a side surface of the support holder 30. Then, the handrail 5 with the handrail holding body 20 attached to one end is attached to the universal connector 1a at the end portion. That is, the screw member 17 is loosened, the joint portion 21 of the handrail holding body 20 is inserted into the recesses 12a and 13a from the openings 12b and 13b on one side of the upper body 12 and the lower body 13, and the recesses 12a and 13a on the other side. The spherical member 40 is loaded into the head. Then, the screw member 17 is tightened to such an extent that the handrail holding body 20 is movable.

終端部の自在連結具1aに取り付けられた手摺5の反対側の端部に手摺保持体20を取り付ける。このときはまだネジ部材での固定は行わない。そして、終端部の自在連結具1aの隣に立設された支柱7に取り付けた自在連結具1bの一方側の収容部11にまだ手摺5に固定されていない手摺保持体20のジョイント部21を収容し、ネジ部材17で上部本体12と下部本体13とを手摺保持体20が可動する程度に締め付ける。このとき、手摺保持体20の手摺5に対する取り付け位置を前後させて手摺5の取り付け長さを調整し、手摺5の取り付け位置が定まったら最終的に手摺保持体20を手摺5に固定する。そして、終端部の自在連結具1aの上部本体12と下部本体13をネジ部材17でしっかりと締着する。   The handrail holding body 20 is attached to the end portion on the opposite side of the handrail 5 attached to the universal coupler 1a at the end portion. At this time, the screw member is not yet fixed. Then, the joint portion 21 of the handrail holding body 20 that is not yet fixed to the handrail 5 is attached to the accommodation portion 11 on one side of the universal connector 1b attached to the support column 7 that is erected next to the universal connector 1a at the end portion. The upper main body 12 and the lower main body 13 are tightened with the screw member 17 to such an extent that the handrail holding body 20 can move. At this time, the attachment position of the handrail 5 is adjusted by moving the attachment position of the handrail holding body 20 to the handrail 5, and when the attachment position of the handrail 5 is determined, the handrail holding body 20 is finally fixed to the handrail 5. Then, the upper main body 12 and the lower main body 13 of the universal connector 1 a at the terminal end are firmly fastened by the screw members 17.

次に、自在連結具1bのネジ部材17を少し緩めて他方側の収容部11に別の手摺5の一端に固定された手摺保持体20のジョイント部21を収容し、手摺保持体20が可動する程度にネジ部材17を再び締め付ける。尚、このとき、終端部の自在連結具1aと連結された手摺5は終端部の自在連結具1aにしっかりと固定されているので位置ズレを起こすことはない。自在連結具1bに新たに取り付けた手摺5の反対側の端部に手摺保持体20を取り付ける。このときはまだネジ部材での固定は行わない。そして、自在連結具1bの隣に立設された支柱7に取り付けた自在連結具1cの一方側の収容部11にまだ手摺5に固定されていない手摺保持体20のジョイント部21を収容し、ネジ部材17で上部本体12と下部本体13とを手摺保持体20が可動する程度に締め付ける。上述の場合と同様に、手摺保持体20の手摺5に対する取り付け位置を前後させて手摺5の取り付け長さを調整し、手摺5の取り付け位置が定まったら最終的に手摺保持体20を手摺5に固定する。そして、終端部の自在連結具1aの上部本体12と下部本体13をネジ部材17でしっかりと締着する。そして、この作業を順次繰り返して行う。尚、自在連結具1aと反対側の最終端の自在連結具1のうち手摺保持体20を取り付けない収容部11には球状部材40を装填して固定を行う。最後に、各部のネジ部材の締め具合を確認し弛みやガタがないこと確認する。   Next, the screw member 17 of the universal coupler 1b is slightly loosened, and the joint portion 21 of the handrail holding body 20 fixed to one end of another handrail 5 is accommodated in the other accommodation portion 11 so that the handrail holding body 20 is movable. Then, the screw member 17 is tightened again to such an extent as possible. At this time, the handrail 5 connected to the universal connector 1a at the end portion is firmly fixed to the universal connector 1a at the end portion, so that no positional deviation occurs. The handrail holding body 20 is attached to the opposite end of the handrail 5 newly attached to the universal coupler 1b. At this time, the screw member is not yet fixed. Then, the joint portion 21 of the handrail holding body 20 that is not yet fixed to the handrail 5 is accommodated in the accommodating portion 11 on one side of the universal connector 1c attached to the column 7 that is erected next to the universal connector 1b. The upper body 12 and the lower body 13 are tightened with the screw member 17 to such an extent that the handrail holding body 20 can move. Similarly to the above-described case, the attachment position of the handrail 5 is adjusted by moving the attachment position of the handrail holding body 20 relative to the handrail 5, and when the attachment position of the handrail 5 is determined, the handrail holding body 20 is finally attached to the handrail 5. Fix it. Then, the upper main body 12 and the lower main body 13 of the universal connector 1 a at the terminal end are firmly fastened by the screw members 17. Then, this operation is sequentially repeated. In addition, the spherical part 40 is loaded and fixed to the accommodating part 11 which does not attach the handrail holding body 20 among the universal couplers 1 of the last end on the opposite side to the universal coupler 1a. Finally, check the tightness of the screw members at each part and confirm that there are no slacks or play.
